Timothy is encouraged to fan into flame the ministry that he has. I think all of us know about getting oxygen into the fire. Anyone that has ever made a fire knows how important it is to get as much oxygen in there as possible. Thus, we wave madly about with newspaper or in the old days people had bellows to make the fire of the Smithy hot enough to melt, bend and temper metal. Who was to do that? Timothy was to do that! Timothy was to take responsibility for his own spiritual growth as a Christian.
